Abstract

Word order flexibility is one of the distinctive features of SOV languages. In this work, we investigate whether the order and relative distance of preverbal dependents in Hindi, an SOV language, is affected by factors motivated by efficiency considerations during comprehension/production. We investigate the influence of Head–Dependent Mutual Information (HDMI), similarity-based interference, accessibility and case-marking. Results show that preverbal dependents remain close to the verbal head when the HDMI between the verb and its dependent is high. This demonstrates the influence of locality constraints on dependency distance and word order in an SOV language. Additionally, dependency distance were found to be longer when the dependent was animate, when it was case-marked and when it was semantically similar to other preverbal dependents. Together the results highlight the crosslinguistic generalizability of these factors and provide evidence for a functionally motivated account of word order in SOV languages such as Hindi.

是什么决定了印地语词性依存词的顺序?效率在理解和生产中的作用

词序灵活性是SOV语言的显著特征之一。在这项工作中，我们调查了印地语，一种SOV语言，语前依存的顺序和相对距离是否受到理解/生产过程中效率考虑的因素的影响。我们研究了头部依赖互信息(HDMI)、基于相似性的干扰、可及性和大小写标记的影响。结果表明，当动词与其依存词之间的HDMI值较高时，语前依存词仍保持在动词头部附近。这证明了局部性约束对SOV语言中依赖距离和词序的影响。此外，当依存关系是有生命的，当它是大小写标记的，当它在语义上与其他言语前依存关系相似时，发现依赖距离更长。总之，这些结果突出了这些因素的跨语言普遍性，并为印地语等SOV语言中词序的功能动机解释提供了证据。
